Need advice for my future

Need advice for my future I am at a really bad situation at my professional career and trying to make a decision about doing certifications and etc. While researching about the relevant certifications it was said that the people holding that certification usually has to present his workings and findings infront of many people. Now what I wanted to ask is does anyone in r/stutter have a job like this where they have to present professionally and most probably in corporate. Let me know your experiences so I can make a informed decision. This is a request to please help me out as I have to make a decision for my career. Thank you
